2014-12-06EUGENE KELLER:Hello. ,yes it
should unscrew relatively easily. If you find it is tite,when you put it back on wipe some silicone grease lightly around the rim.this should prevent it sticking next time.

2014-12-06BRITTON COOKE:Yes. Very easy.

2014-12-06GEORGE COURANZ:I don't drain the filter for the winter. I draw my antifreeze through the strainer and into the engine exhaust cooling system using the engine pump. I have a valve that allows me to pull fluid from the normal cooling water or an open hose. The simple winterization is the main reason but in case there is hull damage and the bilge pumps wont handle it, I can also pump water out of the bilge through my two engines and overboard.

2014-06-03A shopper asked:I am looking at instilling this inline filter to our system. The seawater pressure is 7 bar. Is this filter rated for this pressure?

2014-06-03GEORGE COURANZ:This is a question that should be referred to the manufacturer. 1 Bar is one atmosphere of pressure so 7 bar is about 100 psi. I use my strainer in the cooling water flow for an 85 hp diesel engine. Contact Groco to determine safe use.

2012-08-09EVIE HOPKINS asked:Where can I find a mounting bracket for this ARG-750 raw water strainer?

2012-08-10Nathan Fournier:The strainer comes with the mounting bracket, so you can get a brand new one with the bracket's included, or if you just want the brackets you will need the "GRO-ARG-505" upper bracket and the "GRO-ARG-504" lower bracket, both of which we can get for you and they're only $6.72 each, I also highly recommend getting a new mounting strap with that which is the "GRO-ARG-502" for only $3.36, thank you.

2012-08-11Evie Hopkins:Thanks Nathan. After asking the question I found the brackets could be purchased separately.
Really appreciate your help.

2012-01-24GEORGE COURANZ:I just installed two new raw water strainers on my two perkins 4.236 diesels. I looked all over the place (Perkins shop manuals, etc) to determine how much water flow I needed without success. One of the best engine guys in town said that I could match the engine input water pipe (diameter) to the strainer input and output ports (dia). That would provide sufficient water flow even at extended RPM operation. You could go one diameter size larger on the strainers but the engine input line will cut the overall flow back to the max it can accept.
We have tested both engines. The stbd engine just got a new manifold heat exchanger and the heat exchanger was professionally cleaned. No sign of overheating at extended run. The engine that has not yet had the heat fixed still runs within limits but is noticeably hotter that the stbd engine. So when you do the strainer upgrade, get your raw water exchanger system cleaned out at the same time for max performance.

2012-01-25DON WOGAMAN:I have Groco ARG raw water strainers on both my engine and utility sea water intakes. I have learned that the monel or plastic baskets are most suitable as the stainless basket will fail within a year in salt water. I would suggest the one inch strainer for your engine intake, to assure that grass etceteras will pass through the plumbing and in to the strainer without clogging elsewhere. My Groco ARG with monel basket, one inch size, engine raw water strainer was installed in 1984 and has about 4,000 engine hours on it with no problems. I would recommend a tee on the inlet with an engine zinc, whatever size your engine uses, to protect the bronze from corrosion.
